In Reply to: Instument cluster giving inacurate readings posted by Scott Wilson on August 07, 2001 at 12:35:51:


I've a 88 735i, and already replaced the "printed circuit board" 2 years ago. The replacement fixed the haywire guage issue and the Odo looses memory issue. Now, after a long stint in the garage, my fuel, temp, and tacho guages are screwey. The fuel and temp go to 1/5th of full scale and never move. The OBC knows the fuel level because the range seems to work. The temp is ???. The Tacho doesn't read anything. What could be wrong? Any help would be greatly appreciated.

Remove the instrument Pod and on the back of it, on the right hand side(I think!) there should be a small black plug,with three prongs coming from it.
This is your voltage Stabiliser and controls the amount of voltage going into the Pod. Another way to check is to rev the engine, the instruments may move with reving, also a sign of failure.

Just a suggestion.....
